Chidambaram was arrested by the CBI on August 21 in the INX Media corruption case.
On Wednesday, Chidambaram was produced before the court through video conference as the lawyers are on strike. The court extended his judicial custody till November 27 in the INX Media money laundering case filed by the Enforcement Directorate.
The Central Bureau of Investigation, on 15 May 2017, had registered an FIR against Chidambaram for alleged irregularities in the Foreign Investment Promotion Board clearance provided to INX Media for receiving overseas funds to the tune of ?305 crore in 2007 when he was the finance minister.
The money laundering case was registered by the ED in 2018.
Earlier, disposing off Chidambaram's bail plea, the Delhi High Court had directed Tihar Jail authorities to provide him clean surroundings, mineral water, home-cooked food and protection from mosquitoes.
The court had also directed that Chidambaram's medical check up be done regularly.
